LETTER FROM THE CHAIRMAN

[Photo of Jeffrey L. Shames]
     Jeffrey L. Shames

Dear Shareholders,
Over 75 years ago, MFS invented the mutual fund, giving Americans greater
access to the investment markets. Since then, we have been guided by a number
of fundamental principles, including diversification and professional
management backed by MFS(R) Original Research(SM), a process by which we seek
long-term investment opportunities.

We have found that these principles have matched those of our shareholders. In
a recent survey for MFS by Roper Starch Worldwide, Inc., a major consumer
research firm, over 60% of mutual fund shareholders said they are investing
for long-term goals such as retirement. The survey also showed that investors
realize that the extraordinary stock market gains of the past few years cannot
be sustained. These views certainly seem to have guided investors during last
year's market correction. Beginning with the collapse of Asian markets at the
end of 1997 and continuing with the volatility in U.S. markets through
October of 1998, only 7% of mutual fund investors took money out of the stock
market.

We are even more pleased that MFS investors reacted calmly to last year's
market turmoil, indicating their commitment to diversification. As a result,
throughout the late summer and fall of 1998, daily purchases of MFS stock and
bond funds were well ahead of redemptions.

Over the past year or so, however, diversified investment programs have not
financially rewarded investors. A very narrow band of about 25 stocks
representing the largest U.S. growth companies has, until recently, vastly
outperformed the rest of the market. In 1998, for example, the return on the
Standard & Poor's 500 Composite Index (a popular, unmanaged index of common
stock total return performance) increased 28.58%. However, over half of the
stocks in the index returned less than 10%, including 198 stocks that posted
negative returns.

While 1997 and 1998 were good years for large-company growth stocks, 1996 was
dominated by the mid-sized value category. Prices of value stocks do not fully
reflect the companies' underlying values or future prospects. In 1995, the
best-performing sector was small-company growth stocks. We believe this change
of market leadership shows that while diversification may not provide the best
performance in the short run, it should benefit investors over the long term. In
fact, as 1999 progresses, we are seeing signs of renewed strength from a broader
group of industries, including electric utilities and paper products and
chemical companies. We believe our diversified MFS Family of Funds(R), supported
by Original Research, is well positioned to benefit from a broader market.

Most mutual fund investors refrain from trying to predict short-term trends.
Despite the large stock market gains of the past several years, the Roper
Starch survey shows that people do not see performance as the only
reason to invest. These investors also cite a desire to put investment
decisions in the hands of experts, a belief that mutual funds can be less
risky than other investments, and an appreciation of the convenience of mutual
fund investing.

We appreciate the fact that our fund shareholders and their advisers share our
belief that mutual fund investing is not a way to speculate in the markets but
is a way to use the investment markets to help them work toward their long-
term goals. Our goal at MFS is to offer professionally managed investment
products with the potential to sustain returns over a variety of market
cycles.

We thank you for your confidence and welcome any questions or comments you may
have.

    Respectfully,

/s/ Jeffrey L. Shames

MANAGEMENT REVIEW AND OUTLOOK

[Photo of James J. Calmas]
     James J. Calmas

For the 12 months ended April 30, 1999, Class A shares of the Fund provided a
total return of 4.26%, Class B shares 3.48%, Class C shares 3.23%, and Class I
shares 4.28%. These returns include the reinvestment of distributions but
exclude the effects of any sales charges.

During the same period, the average short-term investment-grade debt fund
tracked by Lipper Analytical Services, Inc., an independent firm that reports
mutual fund performance, returned 5.10%. The Fund's results also compare to a
6.04% return for the Lehman Brothers One- to Three-Year Government/Corporate
Bond Index (the Lehman Index), an unmanaged index of coupon-bearing U.S.
Treasury issues, debt of agencies of the U.S. government, and corporate debt
rated "Baa" or higher by Moody's Investors Service, Inc.

Q. WHAT FACTORS CONTRIBUTED TO THE FUND'S UNDERPERFORMANCE?

A. Most of the problems came in the fourth quarter of 1998, but the Fund's
   relative performance has improved in the past few months. The main problem
   was a continuation of the decline in emerging markets. This decline
   resulted in massive sales of corporate bonds by institutional investors who
   had borrowed to buy emerging market bonds. The Fund had large positions in
   corporate bonds. Holdings in some home equity lending companies were among
   the hardest hit by the disruptions in the credit market. Those positions
   detracted from our overall performance.

Q. WHAT ARE YOU DOING TO HELP IMPROVE PERFORMANCE?

A. Even before the credit market turmoil, we had begun a steady effort to
   upgrade the credit quality of the portfolio. Although higher-rated bonds
   have somewhat lower yields, their prices should be less volatile when
   interest rates rise. We are continuing to upgrade the credit quality of our
   portfolio. A year ago, the average credit quality, based on ratings from
   either Moody's Investors Service or Standard & Poor's Corporation, was
   "A-;'" it is now "A+."

Q. IN UPGRADING FROM "A-" TO "A+," WHAT ISSUERS HAVE YOU SOLD AND WHAT HAVE
   YOU BOUGHT?

A. While cutting our home equity exposure, we increased our holdings in energy
   and telecommunications. For example, we bought Boston Edison, an electric
   utility; Columbia Gas Systems, a natural gas pipeline company; Occidental
   Petroleum, an oil company; and Sprint Spectrum, which is Sprint's cellular
   phone division. We believe all of these companies are in stronger financial
   shape than the home-equity lending companies, and none are as reliant on
   the bond markets for financing.

Q. HAVE YOU SOLD ALL OF YOUR CONSUMER FINANCE HOLDINGS?

A. No. We kept some companies that we think have done a better job of
   evaluating the credit quality of their borrowers, as well as companies that
   don't rely so much on the bond markets to raise capital. For example, we
   own Providian National Bank, a leading provider of credit cards.

Q. HOW DOES THE FUND REFLECT YOUR VIEWS ON FIXED-INCOME MARKETS AND
   INTEREST RATES?

A. We think the strong economy should help corporate debt. The strength of
   industries such as housing, autos, and technology is providing momentum to
   the economy and, with inflation in check, we think interest rates should
   remain relatively stable. For that reason, the Fund's sensitivity to
   interest-rate changes is about the same as that of the Lehman Index. That
   means we don't have too many long-maturity bonds whose prices would decline
   if interest rates increased, nor do we have too many short-maturity (but
   low yielding) bonds. If interest rates do increase, or if there is an
   unexpected event such as the emerging market crisis of 1997-98, we believe
   the portfolio's increased credit quality should help limit a decline in the
   price of the Fund.

NOTES TO PERFORMANCE SUMMARY

Class A share ("A") SEC results include the maximum 2.50% sales charge. Class
B share ("B") SEC results reflect the applicable contingent deferred sales
charge (CDSC), which declines over six years from 4% to 0%. Class C shares
("C") have no initial sales charge but, like B, have higher annual fees and
expenses than A. C SEC results reflect the 1% CDSC applicable to shares
redeemed within 12 months. Class I shares ("I") have no sales charge or Rule
12b-1 fees and are only available to certain institutional investors.

B and C results include the performance and the operating expenses
(e.g., Rule 12b-1 fees) of A for periods prior to the inception of B and C.
Because operating expenses of B and C are higher than those of A, B and C
performance generally would have been lower than A performance. The A
performance included in the B and C SEC performance has been adjusted to
reflect the CDSC generally applicable to B and C rather than the initial sales
charge generally applicable to A.

I results include the performance and the operating expenses (e.g., Rule 12b-1
fees) of A for periods prior to the inception of I. Because operating expenses
of A are greater than those of I, I performance generally would have been
higher than A performance. The A performance included in the I performance has
been adjusted to reflect the fact that I have no initial
sales charge.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Subsidies and
waivers may be rescinded at any time. See the prospectus for details. All
results are historical and assume the reinvestment of dividends and
capital gains.

INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. PAST PERFORMANCE
IS NO GUARANTEE OF FUTURE RESULTS.

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization
MFS Limited Maturity Fund (the Fund) is a diversified series of MFS Series
Trust IX (the Trust). The Trust is organized as a Massachusetts business trust
and is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company.

(2) Significant Accounting Policies
General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues, are valued on the
basis of valuations furnished by dealers or by a pricing service with
consideration to factors such as institutional-size trading in similar groups
of securities, yield, quality, coupon rate, maturity, type of issue, trading
characteristics, and other market data, without exclusive reliance upon
exchange or over-the-counter prices. Short-term obligations, which mature in
60 days or less, are valued at amortized cost, which approximates market
value. Securities for which there are no such quotations or valuations are
valued at fair value as determined in good faith by or at the direction of the
Trustees.

Repurchase Agreements - The Fund may enter into repurchase agreements with
institutions that the Fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the Fund to obtain those
securities in the event of a default under the repurchase agreement. The Fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the Fund
under each such repurchase agreement. The Fund, along with other affiliated
entities of Massachusetts Financial Services Company (MFS), may utilize a
joint trading account for the purpose of entering into one or more repurchase
agreements.

Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All discount
is accreted for financial statement and tax reporting purposes as required by
federal income tax regulations. Interest payments received in additional
securities are recorded on the ex-interest date in an amount equal to the
value of the security on such date.

Fees Paid Indirectly - The Fund's custody fee is calculated as a percentage of
the Fund's month end net assets. The fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

The Fund files a tax return annually using tax accounting methods required
under provisions of the Code, which may differ from generally accepted
accounting principles, the basis on which these financial statements are
prepared. Accordingly, the amount of net investment income and net realized
gain reported on these financial statements may differ from that reported on
the Fund's tax return and, consequently, the character of distributions to
shareholders reported in the financial highlights may differ from that
reported to shareholders on Form 1099-DIV.

Distributions to shareholders are recorded on the ex-dividend date. The Fund
distinguishes between distributions on a tax basis and a financial reporting
basis and requires that only distributions in excess of tax basis earnings and
profits are reported in the financial statements as distributions from paid-in
capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits, which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or net realized gains.
During the year ended April 30, 1999, $42,049 was reclassified from
accumulated distributions in excess of net investment income to accumulated
net realized loss on investments due to differences between book and tax
accounting for mortgage-back securities. This change had no effect on the net
assets or net asset value per share.

At April 30, 1999, the Fund, for federal income tax purposes, had a capital
loss carryforward of $9,938,324 which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration on April 30, 2003, ($3,619,464), April 30, 2005, ($1,432,459),
April 30, 2006, ($549,779), and April 30, 2007, ($4,336,622).

Multiple Classes of Shares of Beneficial Interest - The Fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the Fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. No class has
preferential dividend rights; differences in per share dividend rates are
generally due to differences in separate class expenses. Class B shares will
convert to Class A shares approximately eight years after purchase.

(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with MFS to
provide overall investment advisory and administrative services, and general
office facilities. The management fee is computed daily and paid monthly at an
annual rate of 0.40% of the Fund's average daily net assets.

The Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive
remuneration for their services to the Fund from MFS. Certain officers and
Trustees of the Fund are officers or directors of MFS, MFS Fund Distributors,
Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Fund has an unfunded
defined benefit plan for all of its independent Trustees and Mr. Bailey.
Included in Trustees' compensation is a net periodic pension expense of $4,096
for the year ended April 30, 1999.

Administrator - The Fund has an administrative services agreement with MFS to
provide the Fund with certain financial, legal, shareholder servicing,
compliance, and other administrative services. As a partial reimbursement for
the cost of providing these services, the Fund pays MFS an administrative fee
at the following annual percentages of the Fund's average daily net assets:

            First $1 billion                               0.0150%
            Next $1 billion                                0.0125%
            Next $1 billion                                0.0100%
            In excess of $3 billion                        0.0000%

Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$69,462 for the year ended April 30, 1999, as its portion of the sales charge
on sales of Class A shares of the Fund.

The Trustees have adopted a distribution plan for Class A, Class B, and Class
C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as
follows:

The Fund's distribution plan provides that the Fund will pay MFD up to 0.35%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of the Fund related to the
distribution and servicing of its shares. These expenses include a service fee
paid to each securities dealer that enters into a sales agreement with MFD of
up to 0.25% per annum of the Fund's average daily net assets attributable to
Class A shares which are attributable to that securities dealer and a
distribution fee to MFD of up to 0.10% per annum of the Fund's average daily
net assets attributable to Class A shares. MFD retains the service fee for
accounts not attributable to a securities dealer, which amounted to $16,205
for the year ended April 30, 1999. Fees incurred under the distribution plan
during the year ended April 30, 1999, were 0.15% of average daily net assets
attributable to Class A shares on an annualized basis. Payment of the
remaining 0.10% per annum Class A service fee and of the 0.10% per annum Class
A distribution fee will be implemented on such date as the Trustees of the
Trust may determine.

The Fund's distribution plan provides that the Fund will pay MFD a
distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and
Class C shares. MFD will pay to securities dealers that enter into a sales
agreement with MFD all or a portion of the service fee attributable to Class B
and Class C shares, and will pay to such securities dealers all of the
distribution fee attributable to Class C shares. The service fee is intended
to be consideration for services rendered by the dealer with respect to Class
B and Class C shares. MFD retains the service fee for accounts not
attributable to a securities dealer, which amounted to $2,613 and $97 for
Class B and Class C shares, respectively, for the year ended April 30, 1999.
Fees incurred under the distribution plan during the year ended April 30,
1999, were 0.92% and 1.00% of average daily net assets attributable to Class B
and Class C shares on an annualized basis, respectively. Except in the case of
the 0.25% per annum Class B service fee paid upon the sale of Class B shares
in the first year, the Class B service fee is 0.15% per annum and may increase
to a maximum of 0.25% per annum on such date as the Trustees of the Trust may
determine.

Certain Class A and Class C shares are subject to a contingent deferred sales
charge in the event of a shareholder redemption within 12 months following
purchase. A contingent deferred sales charge is imposed on shareholder

INDEPENDENT AUDITORS' REPORT

To the Trustees of MFS Series Trust IX and Shareholders of MFS Limited
Maturity Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of MFS Limited Maturity Fund (one of the series
constituting MFS Series Trust IX) as of April 30, 1999, the related statement of
operations for the year then ended, the statement of changes in net assets for
the years ended April 30, 1999 and 1998, and the financial highlights for each
of the years in the five-year period ended April 30, 1999. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned at
April 30, 1999 by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS Limited Maturity
Fund at April 30, 1999, the results of its operations, the changes in its net
assets, and its financial highlights for the respective stated periods in
conformity with generally accepted accounting principles.
