Anyone who invests in private funds or owns part of a business knows the pattern. The Schedule K-1 that reports your share of an entity’s income arrives in late summer, sometimes September, long after the rest of your tax information. Extending the return handles the filing. It does not answer the more pressing question: how much to pay, and when, while the numbers are still unknown.
An extension moves the filing, not the payment
An automatic extension gives an individual until October 15 to file, but it does not extend the time to pay. Tax still owed after April 15 generally accrues interest and can bring penalties. A late K-1 therefore creates a real decision in April: pay an estimate based on what is known, or risk underpaying. The same is true of the quarterly estimates during the year.
- Jan 15Final estimated payment for the prior year
- Mar 15Partnership and S corporation returns due; K-1s go to owners unless the entity extends
- Apr 15Individual and trust returns due; first estimated payment
- Jun 15Second estimated payment
- Sep 15Extended partnership and S corporation returns and their K-1s; third estimated payment
- Sep 30Extended trust and estate returns
- Oct 15Extended individual returns
Federal dates for calendar-year filers. California’s individual estimated payments are usually due 30 percent in April, 40 percent in June, none in September and 30 percent in January, with exceptions such as annualized income. A date that falls on a weekend or legal holiday moves to the next business day. An extension of time to file is not an extension of time to pay.
Estimating what has not arrived
Suppose a client holds interests in three funds. Two send estimates in March, and the third has historically sent its K-1 in September. Using the two estimates, the third fund’s pattern in prior years and what its manager has reported during the year, we can build a range and set the April payment toward the upper end if cash allows. When the final K-1s arrive, we compare them with the assumptions and rerun the projection only where the difference matters.
Taxable income and cash also part ways here. A partner is taxed on their share of partnership income whether or not the partnership distributes any cash, so a fund that reports a large gain may still send little money. That is worth knowing before the payment is due.
In spring, the useful preparation is simple: a list of every entity expected to send a K-1, when each arrived last year, whether it provides an estimate, and which payments or decisions depend on it. With that list, the April payment becomes a decision made with open eyes.
Trusts and states have their own timing
A trust’s K-1 follows the trust’s own timeline and the trustee’s distribution decisions. Funds that operate in several states can also create filing obligations in states where the investor has never lived. Both are easier to plan for when they appear on the calendar in spring instead of arriving as surprises in October.
